UPetHook

EthereumRegistered

A tamagotchi-themed hook that applies a variable swap tax (1% when the pet is healthy, 5% when sick/dead) via afterSwap delta return. Buy taxes burn the paired token; sell taxes accumulate in a treasury. Permissionless skill functions (feed, play, clean) let anyone spend the treasury to restore pet vitals and burn more tokens.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
